VALVE,

Specification of Letters Patent.

Patented Feb. 11, 190s.

Application filed April 12| 1907.v Serial No. 367.856.

T o all whom it may concern: l

Be it known that I, EDWIN E. SLICK, of Pennsylvania, have invented a Iiew and useful Valve, of which the following is a full, clear, and exact description, reference beinghad to the aocompanying drawings, forming part of this specification, in whichM y Figure 1 is a cross-section of the headof the blowing engine showing my `improved valves in position; Fig. 2 is a plan view of one i of the valves partlyin section on the line II-II of Fig. 3; Fig. 3 is a side view of the same partly in section; and Fig. 4 is a side elevation of the valve cage with the back stops removed. l

My invention relates tovalves for blowing engines', compressors, pumps, etc., and is designed toprovide a valve which will give a large port area; and also avoid shar l changes in the direction of flow'of the fluir whether water, air., or other fluid.

i vIn the drawings, Figs. 2, 3 and 4 showin detail, the preferred form of one of my valves.

The valve cage 2 is preferably in the f orm of a frustum of a pyramid `having a series of ilat inclined sides, ofwliieh there may be any desirable number, four being shown in the present instance. This cage is hollow, and each oi' its side faces-is provided with slots 3,

lof which I have shown live in number, in

Fig. 4. The head 4 of the cage is solid, and

is preferably provided with an inwardly-projecting ridge-shaped deflector 5.

In the form shown, this dellector is of general pyramidal shape having flat sides, which aid in Idirecting the current of air or4 other Huid through thesideports. This deflector avoids the presence of a dead air space within the cage, and also serves to direct the streams of liuid. l

.The ports for each face of the cage are con* trolled by flat valves 6 which are preferably in the form of thin flexible steel plates or sheets. of which there may be either one or more for each valve. In the present case I show two of these plates, and I prefer to use va plurality in this manner, as the valve is thus made stronger, while at the saine time it is easily flexed back under the ressure of the iluid. In order to avoid the iability of breaking these valves by opening them backwardly too great a distance, I employ back stops 7 which preferably are provided with curved faces to contact with the valve as it is bentbacli in opening the ports. I have shown these back stops `as provided withbase flanges or blocks,v by which they are bolted `to the portion 9 of'the cage. The valve plates are also preferablyprovided with flanges 1() which are held between the back .stop and the portion 9 of the valve cage.

These valves ma however be secured in N any other desirab e manner.

ln Fig; 1, 11 represents the hollow head of a blowinengine provided with my valves, 12 being t e outlet-to the receiver.` Any desirable number of'these valves may be employed in the head, depending on the size of the head, etc. f

In the operation of the device, as the piston is moved toward the head containing these valves, the pressure of the iluid bends the valves backwardly a ainst their back sto s, and the streams of uid iiow longitudinally through the `valve cages and ports into the inner 0X.- As the piston moves in the opposite direction, the valves close by reason l of their resiliency.

The advantages ol' my invention result from'the large outlet area obtained, and also from the avoiding of shar changes in the direction of flow of the ilui passing through the valves.

Many changes may be made in the form and arrangement of the valve cage, the valve, etc., and the valve may be employed either as an inlet or an outlet valve upon pumps, blowing engines, etc.

1. In a pump, a pump cylinder having a head or wall with an opening therethrough,

a projecting cage secured over the opening and having at least three sides rovided with side ports, and valves control ing said side ports, said valves having free outer ends arranged to move awa from the cage Walls in opening; substantial y as described.

2. In a ump, a pump cylinder having a head or wa l with an opening therethrough, a projectingcage secured over the opening and iavi'ng. at least three sides provided with side ports, and valves controlling said side ports, said valves comprising flexible sheets with free outer ends arranged to move away from the cage walls .in opening; substantially as described. l

3. In a' pump, a pump cylinder having a "header wa l with an opening therethrough, a

having at least three sides provided with side ports, valves controlling said side ports, said valves having free outer ends arranged to move away from the eage walls in opening,

Aand back stops arranged to limit the opening movements of the valves substantially as described.

4.A Ina pump, Aa cylinder head or wall havy ing an opening therethrough, a hollow cage secured over the o ening and havin side ports, a valve contro ling said ports an cornprising flexible plates secured at their inner ends with free outerfends coperating with the side ports, and stops arranged to limit the ybackward lmovement of said sheets in opening; substantiall as described.

5. 1n a pump, a ey 'nder head or wall havingan opening therethrough, a hollow cage secured over the opening and havin side ports, a valve controlling said ports an( cornprising flexible plates secured at their', inner 'ends with free outer ends coperating with the side ports, and curved stops arranged to and comprising limit the backward movement of said sheets in opening; substantiallyias described.

6'. In a pump,` a cylinder head or wall having an opening therethrough, a hollow cage secured over the opening and having side described.

In testimony whereof, I have hereunto set my hand.
